Arthroscopic Foveal Reattachment of the Triangular Fibrocartilage Complex (TFCC) with Transosseous Sutures and Anchor Fixation

Abstract

Injuries to the triangular fibrocartilage (triangular fibrocartilage complex or TFCC) are common, and they can manifest with ulnar‐sided pain and a decrease in muscle strength, particularly under load during pronation‐supination move‐ ments. For diagnosis, the most reliable clinical signs are the fovea sign and ballottement. Among the most commonly used classifications for TFCC injuries are those by Palmer, Atzei, and Schmitt. In cases of injuries with persistent symptoms after conservative treatment or injuries with associated instability of the distal radioulnar joint (DRUJ), sur‐ gical treatment should be considered, with arthroscopic techniques being preferred for their less invasive nature. The transosseous suture technique, favored by the authors, is presented in the surgical technique video attached to this article. Current arthroscopic techniques yield good results in treating these injuries, and the surgeon’s preference and technical expertise influence their choice.
